- A 1.0 kg pendulum block at the end of a 1.0 m long rope(assume rope has no mass). When the 1.0 kg mass hangs vertically undisturbed it is in contact with a second block that sits on a flat horizontal surface. The coefficient of friction between the second block and the horizontal surface is 0.15 for kinetic friction and 0.40 for static friction. The 1.0 kg mass is pulled back to an angle of 60. degrees with respect to the vertical and let go. At the lowest point in its swing, it hits the block. After the collision (which takes 0.070 seconds) the 1.0 kg block bounces off the second block and swings back up to an angle of 12 degrees. What is the maximum mass that the second block can have if it moves after the collision?arrow_forwardA small block sits at one end of a flat board that is 4.00 m long. The coefficients of friction between the block and the board are μs= 0.450 and μ = 0.400. The end of the board where the block sits is slowly raised until the angle the board makes with the horizontal is α0, and then the block starts to slide down the board. If the angle is kept equal to α0 as the block slides, what is the speed of the block when it reaches the bottom of the board? Express your answer with the appropriate units.arrow_forwardBlock A has a weight of 8 Ib and block B has weight of 6 Ib. They rest on a surface for which the coefficient of kinetic friction is u - 0.2.

There is a constant force from the wind, F_wind, blowing to the right, so the mass is initially at rest, but hanging at an angle Theta from the vertical because of the presence of the wind. Suddenly, spring breaks, and the mass drops under the influence of F_wind (note F_air and F_wind are the same constant vector!) and its weight. If the object (in equilibrium before the spring breaks) is a height H above the ground, how far laterally (in the direction of the wind) does the object hit the ground, L (given theta, k, M, g, H)?arrow_forwardA long ramp made of cast iron is sloped at a constant angle θθ = 52.0∘∘ above the horizontal. Small blocks, each with mass 0.42 kgkg but made of different materials, are released from rest at a vertical height h above the bottom of the ramp. In each case the coefficient of static friction is small enough that the blocks start to slide down the ramp as soon as they are released. You are asked to find h so that each block will have a speed of 4.00 m/sm/s when it reaches the bottom of the ramp. You are given these coefficients of sliding (kinetic) friction for different pairs of materials.

This spring stretches 2.54 cm vertically when a 2.80 kg object is suspended from it. Determine the following. (a) the force constant of the spring (in N/m) What force causes the spring to stretch? What force does the spring exert on the hanging object? Can you write a relationship between these two forces? N/m (b) the distance (in cm) the spring stretches if you replace the 2.80 kg object with a 1.40 kg object What two forces are acting on the object when it reaches equilibrium? How are these forces related? Can you use the relationship between these two forces to find an expression for the desired stretch in terms of other known information? cm (c) the amount of work (in J) an external agent must do to stretch the spring 8.00 cm from its unstretched position How does the work done by the external agent compare to the work done by the spring and to the change in potential energy of the spring? )arrow_forwardA block, initially at rest, has a mass m and sits on a plane inclined at angle theta.
